mame 0.224 astro blaster - 09/08/20 12:18 PM

now netlist audio has been add in mame 0.224 to astro blaster i have noticed game will only run for me at about 30% speed.
does anyone else experience this?

Netlist audio requires more CPU power than samples, so if your PC is old you might experience slow-downs. What kind of CPU do you have?

it is pretty old its a intel core2 6400@ 2.13ghz with 4gb ram and a nvidia geforce 210 graphics card running win 10 all was fine in mame 0.223

it only just manages 120% on a 4ghz i7 from 5 or so years ago, so yeah.. it's rather demanding now.

We are constantly trying to improve on performance. But expecting 30% to increase to 100% is not realistic. The netlist subsystem (and MAME in general) do not really make use of parallel processing - for a number of good reasons to be fair.

But your core2 would not benefit from that. Running win10 with a low-performance geforce 210 has a constant resource usage as well.

There is a small hair of a lag on the speech? Sounds weird. Gotta be my hearing. Saying twice.

I suspect it might not be running 100% on your system. Check skip.speed with F11.
Not much you can do to speed it up currently, but netlist is always being improved and refined.
If the game really matters a lot and your CPU isn't up to the task (my i5 3.2ghz doesn't get 100%, for instance), keeping a copy of 0.223 might be good.

Yeah I'm not worry about it. But the sindbadm have no issues at all. I guess some will have that issue.

Running at 79%-81% here on astro blaster.

Hit F10 speed it up to 87%-94%. Sounds much better after hitting F10.

179.84% at 4.5ghz ??? Wow, It's incredible !!

With my 4790k O.C.'d to 4.8ghz I get roughly 145% 😮

That's because you're on a 4970K and he's on a 6700K.

Re: mame 0.224 astro blaster - 09/16/20 04:38 PM

I know, but according to some benchmarks, the 4790k should get equal or even slightly better single core performance (multicore is another story) than the 6700k using the same clock rate (mine is 4.8ghz)?

If you are curious about some more comparisons see my bench page at http://www.mameui.info/Bench.htm

My nightly builds tend to be a little faster than the official builds for whatever reason.

Hi John,

sure, I'll take a look at your page. Thanks 👍

Couriersud just checked in some changes that roughly triple the performance of this driver without hurting correctness, so the next release should be better for you.

Re: mame 0.224 astro blaster - 09/20/20 07:42 PM

Wow! Great news! Thanks R.Belmont.
Btw. The amount of changes and advances in the last versions of Mame is just incredible.
Many thanks to all devs and congrats. 👍

Re: mame 0.224 astro blaster - 09/21/20 10:28 AM

it might be worth adding one or more of the Sega vector games eg spcfury to your benchmarks if you haven't already, that also took quite a hit so it will be interesting to see how performance changes over time.

Re: mame 0.224 astro blaster - 09/21/20 06:18 PM

Yes, spacfury took the biggest hit (8 am PST build):

mame elim2 -bench 90
Average speed: 357.03% (89 seconds)

mame zektor -bench 90
Average speed: 324.26% (89 seconds)

mame spacfury -bench 90
Average speed: 184.01% (89 seconds)

Re: mame 0.224 astro blaster - 09/21/20 08:49 PM

I added spacfury to the 2020 bench runs. We hit a 97% slowdown w/ the discrete audio. smile

yes i tried with a nighty build and now up from 30% to 61% speed on astro blaster so a vast improvement
